Penrose’s Black Holes & Universe Theory
According to the Nobel Prize winner, the Big Bang didn’t mark the beginning of the universe as we know it, it merely started the next iteration of our universe. In his theory, known as conformal cyclic cosmology, our current conception of the universe is just one of a series of infinite universes that came before it, and which will come after as well.
What Does the Theory Have to Do With Black Holes?
Unlike other famous theories, which lack any observation evidence (the string theory including), Penrose’s theory provides some evidence in observations of the cosmic background radiation and namely, the average background temperature of the entire night sky.
We can see remnant heat from the Big Bang and differentiate bright patches across the sky. According to Sir Roger Penrose, some of those bright spots are radiation emanations from ancient black holes that predate our current universe.
About Penrose’s Nobel Prize
It’s important to mention that Sir Roger Penrose wasn’t awarded because of his theory of conformal cyclic cosmology. He’s primarily awarded for his work and discoveries about black holes.
Albert Einstein wrote a paper in Annals of Mathematics in 1939, doubting that black holes exist in nature. What Roger Penrose did was demonstrate that black holes are a robust prediction of Einstein’s general theory of relativity, and in doing so, invented a new mathematical tool to depict spacetimes now called Penrose diagrams. Not only that, but he also showed that it is possible to extract energy from a spinning black hole as if it was a flywheel.
